Abstract
A pouring sealed explosion-proof compressor comprises a compressor, a pouring sealed casing, epoxide resin composite and connecting cables, and is characterized in that the cables connected with the compressor is sleeved in the pouring sealed casing which is fixedly stuck on the housing of the compressor by epoxide resin composite, and epoxide resin composite is poured into the pouring sealed casing. The pouring sealed explosion-proof compressor has the advantages that the compressor meets the requirements of the national explosion-proof electric standard and simultaneously reduces the production cost, simplifies the production process and reduces the volume.
Description
Technical field
The utility model relates to a kind of explosion-proof compressor of envelope processing type that waters, the especially explosion-proof compressor that can use in the hazardous location that explosive gas may occur.
Background technique
Compressor case is made by steel plate punching press welding, and shell can bear 1.5MP α at least, the pressure that lasts 15min does not leak, motor stator rotor and compressor piston are sealed in wherein jointly, and the outside has only a cable coupling box and high and low pressure side connecting tube (connecting together with refrigeration system).At present, in explosion-proof compressor, the cable Placement is the form of anti-explosion terminal box basically, and the design difficulty of this terminal box is big, complex process, and the manufacture cost height, volume is big.
Summary of the invention
The purpose of this utility model provides a kind of explosion-proof compressor of envelope processing type that waters, its low cost of manufacture, and production technology is simple, and volume is little.
The utility model is achieved like this, it comprises compressor, waters envelope shell, epoxy resin composite, conjunction cable, it is characterized in that, water the envelope shell and pack into the cable that connects compressor, and be adhesively fixed on the compressor case with epoxy resin composite, guarantee the spacing requirement on all directions, casting epoxy resin composite in watering the envelope shell, treat its natural coagulation, it is close that terminal naked cable conductor is sealed by epoxy resin composite, and described epoxy resin composite is mixed by 1: 1 by epoxy resin and polyamide resin.
The beneficial effects of the utility model are: make compressor both satisfy the requirement of national explosion-proof electrification standard, greatly reduce cost of production simultaneously again, simplify production technology, reduce volume.
Description of drawings
Fig. 1 is the structural representation of existing explosion-proof compressor.
Fig. 2 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, in existing explosion-proof compressor, the cable Placement is to be connected on the explosion-proof compressor 2 by anti-explosion terminal box 1 substantially, and the design difficulty of terminal box is big, complex process, and the manufacture cost height, volume is big.
As shown in Figure 2, the technological scheme that its technical problem that solves the utility model adopts is: at first, design one and water envelope shell 3, shell wall thickness is 2mm, material adopts the PV pipe, then, pack into compressor conjunction cable 5, and be bonded and fixed on compressor 2 shells with epoxy resin composite, secondly, requirement according to GB 3836.1-2000 " explosive gas atmosphere electrical installation section 1: general requirement " and GB 3836.9-2006 " explosive gas atmosphere electrical installation the 9th part: pouring type " m " " standard, casting epoxy resin composite 4 in watering the envelope shell (epoxy resin and polyamide resin mixed by 1: 1), guarantee that the distance between naked cable conductor and the composite Free Surface is not less than 3mm, naked cable conductor and the distance of watering between the envelope inner surface of outer cover are not less than 1mm.That uses waters the envelope agent and must meet above-mentioned standard-required, and the test by regulation detect qualified.At last, treat its natural coagulation, the use of can switching on after 24 hours.Making terminal naked cable conductor be watered the envelope agent fully like this seals.
Claims (2)
1, a kind of explosion-proof compressor of envelope processing type that waters, it comprises compressor, waters envelope shell, epoxy resin composite, conjunction cable, it is characterized in that, water the envelope shell and pack into the cable that connects compressor, and be adhesively fixed on the compressor case casting epoxy resin composite in watering the envelope shell with epoxy resin composite.
2, the explosion-proof compressor of envelope processing type that waters according to claim 1, it is characterized in that: epoxy resin composite is mixed by 1: 1 by epoxy resin and polyamide resin.
